To all whom t may concern.'

Be it known that l, Howixno W. Conil, u citizen of the United States, residing et Bluejneket, in the county of Craig nud )Stute of Oklahoma, rhave invented certuin ,new and useful Improvements in 'llnlldenring lit Turn-Tables; und I do hereby deelzire lll@ fOllOWng to be n ilfull, clear, und exuct description of the invention, such :is will enable others skilled in the nrt to which it, appertains to ineke und use the snzne.

This invention relates to improvements in turn tables and luis vfor one ot' its objects., thev provision of u device of this clnirueter especially adapted for supporting drill bite` so that they can be quickly and conveniently connected to the drill bar of a drilling nmchine, thereby olivi-ating the, necensity ot' manually holding and supportingthe drill when making the connection to the drill bur.

Another Object ot' this invention is the provision of e Supporting sill adopted to he positioned over the drill hole ot the well and carrying the turn table, .so that the drill can be placed thereon and coupled to the drill that is disposed over the well hy rotarb ing the turn table.

A further object of thinl invention is the provision of n ball beau-ing bit turn trible of the above stated character, which will loe simple, durable und ellieient, and which may be manufactured und sold nt a comparatively low cost.

Vlfith these and other objects in View es will become more apparent :is the doser-iption proceeds, the invention consists in eer tain novel features of construction, combinetion, and arrangement of parts :is will be hereinafter more fully described :ind claimed.

For a complete understnndingof my invention, reference is to be had to the following description und accompuny/'innr drnw ings, in which- Figure 1 is u side elevation et eflmll heim ing loit turn tnhle constructed in ncei'rrdnnce with my invention,

This connection. he tween the drill bur t3 end the drill hit Y is so that the drill hit Cnn he readily und conveniently detached from the lnrr when de .1' fed. To liuciliinl'e the renun'zil :rnd rooie@ infr of the drill hit 7 to the drill intr fi l here provided n turn tzihle in ulrich, the numeral S represente :t sill haring; :in openl ini;` i) cmnrnunicnting'- with upper und lower recesses .il und lfb "r null hearing' cup lf2 is poeitioued within the iunior rene-1:; il) end includes :t .:yliinlrieul side weil 'lil und :i hol'- toxn well 1l; provided 'with n, central opere ing; l5 in registration with 'the opening; 9 und surrouinied hy un uunulur linnn", lil which co-iperntes willi the vynil l?) in torniing :i rece way to rceeive the hull lnniriiwe l?. in annuler flange "LS in formed upon the upper end or the mill i3 null disposed innzirdly over the will il i'or aiding` in prerentingthe hell lient-ings in the cup from becouungr diriplnced therefrom.

A Split wusnerl ig positionedon the holt. between the lop .vnll of the recess il und the ruit 2l for :riding in locking' the nut :El upon the inrit. fr. oody .'23 oi n lurn trible .Il is prrrvided with n. con

Relatively spaced blocks 28 are secured to the top face of the body 23 in spaced relation thereto by means of bolts 29 and have their opposed faces inclined as illustrated at E30-for the purpose of receiving the cuttingl end of the drill 7.

In operation, when desiring to connect theA drill 7 to the drill bar, the sill 8 is placed over the boards 1 of the well 2 and the cutting end of thedrill 7 is placed against the beveled or inclined faces 30 of the blocks 28 ot' the turn table 24. The drill is then manually held in a vertical position resting upon the turn table and the drill bar 6 is lowered so that the coupling thereof comes in engagement with the upper end of the drill 7 and by rotating the turn table 24: the drill 7 will be connected or threaded into engagement with the drill bar- 6.

While ll have shown and described the Apreferred embodiment of my invention, it

will be understood that minor changes in construction, combination, and arrangement of parts may be made` without departing from the spirit and scope of the invention as claimed.

lNhat l claim as new is 1. Abit turn table comprising a Sill, a body rotatably supported by said sill, and means on said body for engaging the cutting end of a drill so that the drill can be rotated with the body for coupling it to a drill bar. L

2. A bit turn table comprising a sill, a bolt carried by said sill, a bearing cup carried by said sill and surrounding the bolt, a

Lacasse body carried by the bolt and in spaced relation to the sill, ball bearings in said cup, a cone carried by said body and bolt and engaging the ball bearings, and means on said body for receiving the cutting en'd of the bit.

8. A bit turn table comprising a sill having an opening communicating with upper and lower recesses, a bolt extending through the recesses and opening, a nut threaded to the lower end of said bolt and located Within the lower recess, a split Washer onsai'd bolt between the top wall of the lower recess and the nut, ball bearings located within the upper recess, a body carried by the upper end of the bolt, a bearing element carried by said body and resting upon the ball bearings, vand means upon said body for receiving the cutting end of a bit.

4. A bit turn table comprising a sill, a bolt carried by said sill, a cup carried by said sill and surrounding the bolt, ball bearings located in said cup, an annular fiange formed on said cup for retaining the ball bearings therein, a body carried by said bolt and having the head thereof countersunk therein, a bearing element carried by said body and surrounding the bolt, an extension formed on said bearing member and having a concaved face to receive the ball bearings, and means carried by the body for receiving the cutting end of the bit.

5. A bit turn table comprising a sill adapted to be positioned over a well, a body rotatably mounted upon said sill, spaced blocks carried by said body and having cut away faces to receive the cutting end of a bit to permit -the same to be supported and rotated in a vertical plane or coupling connection with a drill bar.

In testimony whereof I aiiiX my signature in presence of two witnesses.
